摘  要：
运用源强系数法对2011年北戴河及相邻地区近岸海域农业面源污染进行测算,并分析北戴河海域农业面源污染特征,旨在为北戴河及相邻地区近岸海域水体污染的防治提供理论依据.结果表明,2011年北戴河及相邻地区近岸海域农业面源化学需氧量(COD)排放量为38 768.27t,总氮(TN)为15 684.63t,总磷(TP)为7 821.18t,其中COD排放量是同年秦皇岛市工业废水中COD排放量的6倍;种植业是N、P污染的主要来源,对TN和TP的贡献率分别为49.10%和85.83%,农村生活源、畜禽养殖业和水产养殖业对COD的贡献率分别为35.84%、33.40%、30.76%;四县农业面源污染明显比三区严重,其中昌黎县农业面源污染最重,北戴河区污染最轻.

摘  要：
By using the data collected in Beidaihe and adjacent areas in 2011,this paper calculated their pollution emissions by pollution discharge coefficient method,and analyzed agricultural non-point source pollution characteristics,aiming to provide a theoretical basis for prevention and control of water pollution in Beidaihe and adjacent areas of coastal waters.The results showed that the COD,TN,TP emission were 38 768.27 t,15 684.63 t and 7 821.18 t,respectively,in 2011.The COD emission of agricultural non-point source pollution was six times higher than that in industrial wastewater in the same year in Qinhuangdao city.Planting was the main source of N and P pollution,and the contribution rate of TN and TP were 49.10% and 85.83%,respectively.The COD contribution rate in rural life,livestock farming and aquaculture was 35.84%,33.40% and 30.76%,respectively.Agricultural non-point source pollution in four counties was more serious than the three districts.In this investigation,agricultural non-point source pollution was the most serious in Changli county,and the lightest was Beidaihe district.
